Serta Mattress Cascade Ridge Plush Mattress - King

The Serta Cascade Ridge Plush Mattress in King size delivers targeted comfort through its innovative 5-zone design that adapts to your body's natural curves while you sleep. At its core, the Q4 Support System features 860 densely-packed interconnected coils that distribute weight evenly and maintain their support for years. CoolTwist gel foam works alongside breathable CoolFeel fabric to actively dissipate heat throughout the night, helping you maintain a comfortable sleeping temperature. The alternating firm and plush zones provide extra support where your back needs it most while cushioning pressure points at your shoulders and hips, making this mattress ideal for side sleepers and anyone seeking a softer feel without sacrificing proper spinal alignment.
